XT-CF20

Our first special filament based on the Amphora 3D polymer. Reinforced with 20% specially sourced carbon fibers, this filament is perfect for parts which need high stiffness. XT-CF20 has a beautiful matte surface finish when printed.


CARBON FIBER IS ABRASIVE:


A special point of attention is the abrasive nature of the carbon fibers. In general these fibers will accelerate the nozzle-wear of brass nozzles, much faster than unfilled filaments. Therefore we  recommend to use hardened steel nozzles.

This is some sexy-smexy stuffReview by Jonas
Quality
If you know your printer a little, have a stainless nozzle and are willing to make the necessary sacrifices, you'll be in for a ride. As with any exotic material, it wants to be treated right. This means not too thin layers (I'd recommend 0.2mm or upwards), speeds below 40mm/s, stainless nozzles larger or equal to 0.4mm diameter, a toasty 260°C on your hotend and a cuddly 65°C on a kapton bed. If all goes well this will leave you with a beautifully matt black, grippy surface on a part as rigid as I've never experienced it before. Think much stiffer than PLA, but you can hit it with a hammer and it won't shatter (within reason, of course).

The only question that remains for me is, what took you so long, Colorfabb? ;) (Posted on 9/8/2015)
Bin enttäuscht Review by Markus
Quality
Das Material ist wirklich sehr sehr Stabil und verspricht lt. dem Video super Druckergebnisse...
Jedoch ist das drucken mit dem CF20 ein Qual. . Jede neue Geometrische Form benötigt ihre eigene sehr sensible Einstellung. 3 Rollen Bestellt. Und nach 5 Tagen dauertest gebe ich auf... Die paar Ergebnisse die nach vielen hin und her gespiele in den Einstellungen erwecken nicht den Eindruck eines Prozesssicheren Materials. Sehr schade.

Fantastic productReview by Mikael

I had great hopes for the carbon fiber reinforced filament and I must confess that I was surprised when I checked the result of my prints. It is really rigid and makes it possible to print parts with demanding mechanical properties. A fantastic product that takes 3D printing to a new level when it comes to mechanical strength.

In-house production
All colorFabb 3d printing filaments are produced in our own production facility, situated in the Netherlands. Since no external parties are involved in the making of colorFabb filament we can ensure consistent quality on every order.

Excellent diameter tolerance
An important machine in our production are the laser measurement systems used to check the diameter of our filament real time during production. It’s measured over 1000 times per second and helps us guarantee that each spool of colorFabb 3d printing filament produced within tolerance. We can guarantee 0,05mm +/- on both 2,85mm and 1,75mm colorFabb 3d printing filament, which means you can rest assured that your printer is extruding the exact amount of material.

Packaging
Within minutes of production a spool of colorFabb 3d printing filament is sealed airtight with a double barrier foil. To go the extra mile, we’ll also seal the fancy cardboard box that we use to ship our product. You can make sure colorFabb 3d printing filament is fresh and ready for 3d printing when you’re done unboxing.

Tips & Tricks

At colorFabb we have a well equipped 3d printing studio with a lot of popular 3d printers. We know our materials will give you excellent results and to help you get these results here are tips and trick for using colorFabb 3d printing filament.

 

Adviced 3d printing temperature:
240-260C

Adviced 3d print speed:
40 - 70 mm/s

Advised Heated bed
60-70C

Build platform
For colorFabb_XT we advice to print on a heated bed. After printing, the build plate needs to cool down to about 20-30 C at which point you can remove the printed part.

Tips & Tricks

At colorFabb we have a well equipped 3d printing studio with a lot of popular 3d printers. We know our materials will give you excellent results and to help you get these results here are tips and trick for using colorFabb 3d printing filament.

 

woodFill

Adviced 3d printing temperature:

195-220C*

Adviced 3d print speed:

40 - 100 mm/s

Advised Heated bed (if you have one, not strictly necessary)

50-60C

 

TIP! For stronger prints and better reliability you can increase flow rate with about 0-10%. This will cause the filament to keep going through the hot zone at a steady pace. Also check out our learn.colorfabb.com website for more information and slicer profiles regarding woodFill.

 

glowFill

Adviced 3d printing temperature:

195-220C*

Adviced 3d print speed:

40 - 100 mm/s

Advised Heated bed (if you have one, not strictly necessary)

50-60C

 

TIP! For a better and longer lasting glow time print your models with 100% infill and charge up your models with some high power lights, or just let them enjoy the sunlight for a bit.

 

bronzeFill

Adviced 3d printing temperature:

195-220C*

Adviced 3d print speed:

40 - 100 mm/s

Advised Heated bed (if you have one, not strictly necessary)

50-60C

 

TIP! Depending on your set-up, 3d printer and slice software, you might see that bronzeFill needs a bit more flow compared to your normal PLA settings. Most plastics will show die swell when coming out of the nozzle tip, this is counteracted with specific slicer settings. Since bronzeFill doesn’t show a die swell such as PLA you might need to increase flow rate a bit, 4-8% was perfect for our UM2. UM original did not need any adjustments.

 

TIP! Sanding and polishing your parts will make the bronze particles shine. Start sanding with grit 120-180 and make sure all the printed lines vanish. You’ll notice that because bronzeFill is easy to sand down, careful you won’t loose too much detail. Then start working your way up by following with grit 240-320 and finishing off with grit 600 - or higher. Finally we used a clean soft cloth and some copper polish to really get all of the shine out of the bronze particles.

 

corkFill


Adviced 3d printing temperature:
210-230C*

Adviced 3d print speed:
40 - 60 mm/s

Advised Heated bed (if you have one, not strictly necessary)
50-60C
 
TIP! For stronger prints and better reliability increase flow rate with about 4 -10%.

 

General Tips

 

Build platform

Our PLA/PHA compound performs well on both heated and non-heated build platforms. For those users printing on a cold build platform we advise applying masking tape to the build area. The rough surface of the tape will provide enough adhesion for the first layer to stick and print almost without any warping.

 

Users using heated build platforms have quite a few options these days. The usual suspects are glass and aluminum build plates. For directly printing on glass or aluminum we advice user to apply glue-stick. A very thin layer will be sufficient to keep your print nicely in place. Another method is dissolving wood glue in water, you the consistency of the substance can be quite thin, a bit like milk. By applying just a few drops and smearing this out before you start heating the built plate will create a very thing layer which holds the woodFill down very well. If applying this method, be careful that you don’t get your electronics wet.

Another method that works well with colorFabb woodFill is polyimide tape, or Kapton tape. This tape is available as a very narrow strip or very wide strips which allow you to cover the build plate in one go. When the tape is applied correctly it can last for months.

TIP! Take your time leveling the bed and adjusting the the gap between 3d printer nozzle and build plate. A perfect first layer will is very important, especially for 3d prints with a large bottom layer. Having the nozzle set to close to the build plate will cause a pressure build up and as a result back flow in most hot ends. 

 

TIP! PLA/PHA has very minimal warping tendencies, however if your printing parts which take up the maximum of you buildspace you might see some warping. If it’s very important that your part is perfectly flat than we suggest to turn down the fan that is cooling your part. This allows the material to slowly get rid of heat without warping. After a few centimeters you can turn on the cooling if the part needs it.

 

*3d printers have lots of different types of hot-end which makes it extremely difficult to give aan temperature advice. We feel our temperature advice holds for most 3d printers, but should be considered as a starting point for you to find the temperatures that work in you setup. Don’t be afraid to go either higher or lower then our advised temperatures if you feel your set-up needs this.
